Abstract: A heat exchanger includes a sensor grid with sensor leads extending through tube restraints for heat exchange tubes in the heat exchanger. The tube restraint includes a body having a plurality of tube openings defined therein with each tube opening receiving one heat exchange tube of the set of heat exchange tubes therethrough. The body also includes a sensor lead opening defined therein to receive a sensor lead therethrough. Each tube opening has a larger dimension than the sensor lead opening. The sensor grid is installed during manufacture rather than in the field, allowing the sensor grid to be on outermost and inner sets of heat exchange tubes in the heat exchanger.

Abstract: Drones are engineered with sensors for use in insurance applications. After locating an object of interest, a drone performs an investigation by probing the object of interest. Sensors receive feedback from the object of interest. An electronic fingerprint of the drone is produced. Afterward, perils are computed based on the feedback and the fingerprint of the drone is used in insuring the object of interest. The act of probing includes thumping, drumming, or radiating ultrasound waves against the object of interest. The sensors can be turned off when they are within a geographic zone of prohibited operations.

Abstract: A system is provided for load testing a lift beam. The system includes a load testing framework configured to support the lift beam, a first connector configured to couple with a lift connector of the lift beam, and a second connector configured to couple with a load connector of the lift beam. The system also includes at least one drive configured to force the first and second connectors away from one another to load test the lift beam.

Abstract: A tube includes a center tube comprising a steel material, a fluid flowing through the center tube; and at least one disk disposed around the center tube, the disk including a thermally conductive material and exposed to an external heat source. The disk conducts heat from the external heat source into the center tube. The center tube transfers the heat from the external heat source into the fluid. The thermal conductivity of the at least one disk is higher than the thermal conductivity of the center tube.

Abstract: A seat assembly includes a seat back frame, a support and a bracket subassembly. The bracket subassembly connects the seat back frame to the support. The bracket subassembly includes a first bracket having a first attachment feature and a second bracket having a second attachment feature wherein the first and second attachment features engage to lock the bracket assembly around the support. A method of securing a seat back frame to a support is also disclosed.

Abstract: A camera mount for supporting a camera unit has a base portion having a first surface, which includes an elongate concave surface feature extending across at least part of the first surface and defining a first axis. Engagement means including a first plurality of protrusions which extend out of, are spaced apart across part of, the first surface, each of the protrusions extending substantially perpendicularly to the axis, and substantially parallel to at least one other of the protrusions. Each of the protrusions defines an aperture therethrough, the apertures being substantially aligned along a second axis, the second axis being substantially parallel to the first axis.
